Well the test restults you listed dont mean much unless you know which tester this seller is using. Also you need to know that the tester being used is properly calibrated. If these tubes are on ebay I would be very careful. Further you need to have a guarantee that the tubes will not have noise or microphonics. What I would do is buy just the Amperex and experiment with them in various positions. In my experience, Amperex 6922s have always bettered the Siemens I have heard. But, the early to mid 1960s Siemens 6DJ8s are excellent as are all the 6DJ8s from Amperex that were made in the same period. Remember that in about 95% of applications, 6DJ8s can be used in place of 6922s. At the price of 6922s, I would opt for 6DJ8s. Having said this make certain that you circuit wasnt specifically designed to run 6922s, which I am almost certain the Audio Research was not.
